Nikon F (DX/FX)

Review

The Sigma 17-70mm F2.8-4 DC Macro OS HSM is a versatile and compact lens designed specifically for Nikon F (DX) mount cameras. This lens is an excellent choice for photographers who need a reliable all-rounder for various situations, from landscapes to portraits and macro photography. With its effective focal range of 17-70mm, it covers a broad spectrum suitable for many shooting scenarios.

Build Quality and Design

One of the standout features is its solid build quality. The lens feels durable and well-constructed, featuring a metal mount that adds to its robustness. The compact design makes it easy to carry around, perfect for those who frequently travel or shoot on location. Weighing approx. 565 grams, it is relatively light for a zoom lens of this kind, making it easy to handle for extended periods.

Optical Performance

When it comes to image quality, the Sigma 17-70mm excels with its sharpness and contrast. The lens performs particularly well in the center of the frame, even at wide apertures. On the other hand, corner sharpness is good but can soften slightly, especially at the 70mm end. The F2.8-4 maximum aperture allows for decent low-light performance, though it’s worth noting that f/4 may not suffice in dim conditions without a proper boost in ISO.

Macro Capability

The macro capability is another highlight of this lens. It boasts a minimum focusing distance of 20 cm (7.9 inches), allowing photographers to get up close to intricate subjects. The 1:2 maximum magnification ratio does limit true macro photography, but it is sufficient for everyday close-up shots and renders impressive detail.

Image Stabilization

Optical Stabilization (OS) is integrated into this lens, which is particularly beneficial for low-light shooting or when using slower shutter speeds. This technology helps to minimize the effects of camera shake and can be an invaluable asset for handheld photography, ensuring sharp images even under less-than-ideal conditions.

Autofocus Performance

The Hyper Sonic Motor (HSM) provides quick and quiet autofocus, making it suitable for both stills and video shooting. The focusing speed is impressive, and it locks onto subjects quickly, although in some cases, it could struggle in low light or low-contrast scenarios.

It’s well-suited for various photography genres, from landscapes to portraits and even macro work. While it has some minor drawbacks, such as corner softness and a less-than-ideal maximum aperture at longer focal lengths, its strong points make it a worthy addition to any shooter’s kit. If you're in the market for a reliable walk-around lens that won't break the bank, this one deserves a spot in your lens collection.
